AUX System: Effects Send/Receive

The AUX 2 buss of the Multimix 12R is a post-fader send. Usually, you will connect AUX 2 to the input of an effect device. Using a post-fader send means that when you fade a channel out, its effects will fade out also.

Using the aux send allows each channel to have its own level control feeding the aux output (and eventually the input of the effect device). You can make a mix of any channels you want to go to the effects by using the individual channels’ aux send levels.

But sending signal to the effect device is only half the story. To be heard, the output of the effect device must be returned to the mixer and turned up in the mix before you can hear it. You have two options for returning the effected signal to the mix:

•connecting to the STEREO AUX RETURN jack, or

•connecting to the channel LINE IN or STEREO LINE IN jacks.

Connecting to channel inputs gives you the added bonus of panning and EQ on the effects, and the ability to send a “wet” or effected mix to AUX 1 for monitoring.

Wet/dry mix: No matter where you connect the output of the effect unit into the mixer, you are in control of the “wet/dry” balance between the mixer’s channel inputs (the uneffected or “dry” signal), and the effect returns coming from the effect device (the “wet” signal). The output of the effect device should only contain effected signal, and not have any uneffected or "dry" signal mixed with it (since the dry signal is already at the mixer). Consult the manual for the effect device to find out how to set the effect so that only effected ("wet") signal is returned to the Multimix 12R.

How to Set Aux Send and Return Levels

You must set correct levels on the mixer's individual Aux Sends and STEREO AUX RETURN and the effect device's own controls to get good, clean, quiet results.

✪Improper level setting is the most common cause of noise and distortion problems.
